Hello! I apologize in advance if this has been asked before, or if it more properly belongs in the career section - I wasn't sure since I'm still at university. I'm currently in the middle of my undergrad studies in physics with an astronomy focus. My plan has been to go on to grad school to pursue a PhD in astrophysics but the more I talk to people and read about others' experiences the more I think I should plan for contingencies other than being a successful astrophysicist in academia. I love physics in general, and astronomy in particular but I'm also very interested in the nuclear energy side of things. I'm wondering if there's any way that I could pursue the field of astrophysics and still prepare myself for getting into nuclear physics in some way in case things don't work out with the astro side. Or is this entirely unrealistic? Thank you for any advice you can give.
